Efficiency evaluation and influencing factors of Thermoelectric Heat Sink:

The efficiency of the Thermoelectric Heat Sink is a critical factor in measuring its performance. The efficiency of a thermoelectric radiator mainly includes two aspects: thermoelectric conversion efficiency and thermal impedance.

Thermal electric conversion efficiency（ η） It is an indicator that measures the ability of thermal energy to be converted into electrical energy. η The higher the value, the stronger the thermoelectric conversion ability and the better the heat dissipation effect. Thermal impedance (아르 자형) is an indicator that measures the ability of a thermoelectric radiator to conduct heat energy. The lower the value of R, the stronger the ability to conduct heat energy and the better the heat dissipation effect.

Factors affecting the efficiency of Thermoelectric Heat Sink:

1. Properties of semiconductor materials: The thermoelectric coefficient and conductivity of semiconductor materials significantly impact their performance. The higher the thermoelectric coefficient, the stronger the ability to convert thermal energy into electrical energy; The higher the conductivity, the stronger the conductivity of the current, and the better the effect of thermal energy conduction.

2. Shape and size of heat sink: The shape and size of the heat sink significantly impact the distribution of heat flow and heat dissipation efficiency. A reasonable heat sink design can increase the heat dissipation area and improve the heat dissipation effect.

3. Working environment temperature: Working environment temperature also significantly impacts the performance of TEHS. In high-temperature environments, the thermoelectric conversion efficiency and thermal impedance of TEHS will decrease, so appropriate heat dissipation measures need to be taken to maintain its performance.

4. Manufacturing process: The manufacturing process also significantly impacts the performance of TEHS. Advanced manufacturing processes can improve the performance and stability of TEHS while reducing manufacturing costs.
